Data Science Traiee

Ngao Labs • Part-time

Feb 2026 - Present • 3 mos

As a Data Science Trainee at Ngao Labs, I specialise in transforming raw data into actionable insights and interactive web applications. My expertise covers the full machine learning lifecycle, ensuring that models are not just accurate, but ready for real-world use. What I Bring to Your Project: End-to-End ML Pipeline: I manage the entire process, including rigorous data cleaning, exploratory data analysis (EDA), and feature engineering to ensure high-quality model inputs. Model Building & Optimisation: I develop robust machine learning models tailored to specific business problems, focusing on performance, scalability, and accuracy. Interactive Deployment: I don't just deliver scripts; I build and deploy intuitive, user-friendly dashboards using Streamlit, allowing you to interact with your data and model predictions in real-time. Technical Proficiency: Skilled in Python and the core data science stack (Pandas, NumPy, Scikit-Learn) to solve complex data challenges.
